Googled it: P1682 Chevrolet Ignition 1 Switch Circuit 2 OBDII Engine Light Trouble Code | Engine-Codes.com

Yeah I got that far but that didn't get me very much with solving the problem. Thanks

Well since the link provides information on 2 different fuses, I would start there. Your owners book has a listing of the fuses and locations.

Gee; 2 fuses, 1 relay, 1 switch, TAC or the ECM. That doesn't help? Did you scroll down to the bottom:
There are 2 ignition 1 voltage circuits supplied to the Engine Control Module (ECM). The first ignition circuit is provided by the powertrain relay, through a fuse. This ignition 1 voltage circuit supplies power to all the internal ECM circuits associated with the throttle actuator control (TAC) operation. The second ignition 1 voltage circuit is supplied by the run/crank relay through a fuse, and is used to power the remaining internal ECM circuits. If the ECM detects a voltage difference between the 2 ignition 1 voltage circuits, DTC P1682 will set.

Sounds like an exact way to diagnose & the solve to me. My money is on the TAC not being plugged in correctly.

Have you had the ignition switch recall done?

Thanks everyone for the help and info. I found my stupid mistake...Cam Solenoids in the opposite holes.

That'll do it. Glad you got it resolved.

Snoopy

Would have been helpful if you told us you just performed the mechanical work and the car wouldn't start.

But I'm glad it worked out.
